Why is it not recommended to have 2 antivirus programs running at the same time?
In: Technology
Think of your Antivirus as an inspector that each time you request an item will first pick this item up, inspect it for anything that might hurt you and then hands it over to you, IF it passes this inspection. If it doesn’t pass the inspection, the inspector can neutralize it – delete it, put it into quarantine or simply prevent it from working.
Now you hire two inspectors for the same job, and neither of one expects the other inspector to be there. They actually can’t even notice the other inspector, they can only inspect things and nothing else.
Now both those inspectors try to grab the same things to inspect them. This leads to several possible outcomes.
a) one of the inspectors doesn’t get the items “on time” and might decide this counts as a failed inspection, thus blocking that item from working (or deleting it or whatever)
b) both inspectors get the item, both inspect the item, doubling the inspection time.
c) both inspectors run into each other and end up fighting for who gets the item first, either bringing everything to a halt or just slowing everything down, however not doing their work.
d) one of the inspectors might try to inspect the other inspectors stuff. Usually inspectors protect their stuff so no one can meddle with their tools used to inspect items. The inspector inspecting the inspector would interpret this as suspicious and try to delete, quarantine or otherwise block the inspected inspector. The inspected inspector in turn would view this as a very malicious activity, and in turn try to delete or otherwise block the inspecting inspector.
